Plate XVII., iig. 3 
A young specimen from Taufikia, new for the Egyptian Sudan. 
Ventrals, 136 ; subcaudals, 22 pairs ; 6 upper labials. 
Oculars ; 2 prse-, 2 sub-, 1 postoculars on the left. 
2 pree-, 3 sub-, 2 postoculars on the right side. 
Differs from the following species in coloration in the brownish-grey ground colour, 
the larger dorsal spots, the missing black margins of upper labials and different position and 
shape of the nuchal A-shaped marking. 
iJansus resimus, Peters 
Plate XIX 
Three specimens, perfectly adult, from Taufikia, White Nile, the largest 670 mm. 
(tail 70 mm.). Keels of scales very distinct, not reaching much beyond the basal half of the 
scale ; even the keels of the outer row distinct. Scales in 21 rows ; ventrals, 148, 149, 155 ; 
subcaudals, 26, 23, 20 pairs. The total sum of ventrals and subcaudals (174, 172, 175) 
varies, therefore, less than the sum of ventrals or subcaudals taken separately (3 instead 
of 6 or 7) ; a similar number results from the specimens recorded by me in my “ Eeptiles of 
the Sudan” (173, 177). 
The coloration is distinctly green in life, bluish in spirit. 
Upper labials, 7 ; oculars :— 
1. 2 + 2 -f 2, 2 + 1 -t- 1. 
2. 2 + 1 + 1, 2 + 1 -f 1. 
3. 2 -f 1 + 1, 2 -h I -f 1 (on the left side, two postooulars fused with posterior 
subocular ; on the right, two suboculars fused with lower postocular). 
Atractaspis microlepidota , Giinther 
Plate XX., fig. 1 
A specimen, 570 mm. long (tail 40 mm.), from Nasser, Upper Sobat, new for the Egyptian 
Sudan. Scales in 29 rows ; ventrals, 238; subcaudals, 25. This is also the first specimen of 
any species of the genus Atractaspis hitherto known from the Sudan, though two species 
have been recorded from North Uganda (Wadelai).
